What do food labels tell us about what we’re eating?

On today's Your Call, we're talking about food labels like "organic" and "fair trade.” Studies show that sales increase by 10 percent because of food labels. But what do they mean exactly? How are these labels enforced in the US and abroad? As the number of labels increase, how should we measure certification? And how does a label change the way you think about and buy your food? Join the conversation on the next Your Call, with Hana Baba and you.

**We didn't have time to get this caller on, but she wanted to everyone to know about the dangers of citric acid - apparently it does not come from citrus juice but rather is manufactured by an industrial culture of a type of mold called Aspergillus Niger. It can cause severe allergic reactions and asthma and is almost never labeled!!
